Is it really worth buying one of these wedges? or should we just stick to using pillows?

definitely invest in ramp, wedge or both, the experience is way more amazing. Until recently we used just pillows then we got the ramp and will be purchasing wedge this week, once you use one of these you will wonder why you didn't invest sooner.

For kicks, I recently tried our old "g-spot" pillow (just a tube-shaped decorative pillow from Target) instead of Liberator stuff. Total fail! The difference is way more noticeable AFTER using the firm foam stuff, actually.

The Doc Johnson (I believe?) inflatable positional pillows are cheaper, but I think they are like wiggly tiny air mattresses! Doc Johnson and I don't get along often, though

I find that the pillow is less expensive and is more manipulable. The dong does squish down into it, when riding, but that's why it's best to buy a larger dong than necessary for insertion! The balls are another story; I'm scared they'd pop, especially with clawed pets around.
